Poti is a port city in Samegrelo.
Poti is a port city with several operating passenger and cargo ferries that may interest travellers including UKRFerry and Navisped which connect Poti with Ukraine, Bulgaria and Turkey. Routes, dates and prices are constantly liable to change due to regular delays.
On board the Navisped Sevastopol, you will be provided with fantastic food each breakfast, lunch and dinner, including fruit, bread, fish, lots of soups and lots and lots of meat. Bottled water is available, but limited per day. It is recommended to bring your own snacks (biscuits etc.) and most definitely your own alcohol, fruit juices, yoghurts and similar. Nothing is available to buy and you can bring whatever you want on board, although customs at your destination will be thorough. The beds are comfortable, the bedrooms and bathrooms clean and well maintained with powerpoints and a table and chair and all with windows. In the communal areas there is a tv and dvd player, but limited choices on offer and little else in the way of entertainment.
Importantly it must be noted that ferries on the Black Sea are regularly delayed by days at a time and a 4 night trip can easily turn in to a 7 night trip. Regardless, the ferry is an enjoyable and relaxing experience.
The Poti port is currently being renovated and can make navigating the port extremely difficult, however there is a free bus service connecting different parts of the port and enough English-speakers to get by. A taxi from Poti centre or the train station to/from the port should be less than 50 lari, walking could take around 20 minutes.
The airport in Poti has been closed since the collapse of the Soviet Union, however the government is planning to resume service by 2012. As of now Batumi International Airport  is the closest one, with flights from Baku, Istanbul, Kiev, Moscow and Tel Aviv amongst others. However, the number one gateway to Georgia is still via Tbilisi, not too far away.
European road E70, which starts in Spain, has its endpoint here. From Tbilisi, take the M27 road westwards and then turn off to A305 just outside the city of Senaki. A305 continues further to Batumi, so travel from there is straightforward.
Buses are plentiful from nearby Batumi, journey time is just about one hour.
Taxis are cheap and plentiful, although the drivers will not speak any English.
